Neighbor-joining tree of the 16S rRNA gene of MRB220 and selected 16S rRNA gene sequences from members of Stigonematales. All 16S rRNA sequences were aligned with MUSCLE [49], and neighbor-joining analysis with 100 bootstrap replicates was conducted using Geneious Tree-builder [50] based on the Tamura-Nei Model. Bootstrap values are labelled in each branch note and Synechocystis sp. PCC 6803 was used as the outgroup
